Fix BugTracker: match actual API data model

- is_resolved (0/1/2/3) instead of string status
- priority (0/1/2 numbers) instead of strings
- content field instead of title/description
- display_name/username for reporter
- comment endpoint /comment (singular), body: {content}
- Fix duplicate content display in template
